Many of the newfound diseases -- 71% -- started in wildlife and are
becoming more common. Drug-resistant strains of infectious diseases are also on
the rise, note the researchers, who included Kate Jones, PhD, of the Zoological
Society of London.

Most of the infectious disease discoveries were made in Western countries,
and those discoveries peaked in the 1980s. But Jones and colleagues are
particularly concerned about the unknown infectious diseases that are
still out there, especially in countries without the resources for finding
them.

"The benefits would not just be felt locally: in an era of increasing
globalization, emerging infectious diseases are everybody's problem,"
writes Professor Mark Woolhouse, PhD, of the Centre for Infectious Diseases at
Scotland's University of Edinburgh, in an editorial published with the study in
Nature.
